BACKGROUND

Conventionally, surgical procedures performed in a body cavity of apatient, such as the abdominal cavity, required one or more large accessincisions to a patient in order for the surgical team to perform asurgical action. With advancements in medical science and technology,such conventional surgical procedures have been largely replaced byminimally invasive surgery (MIS) procedures and, where applicable,natural orifice transluminal endoscopic surgical procedures (NOTES).Recent developments in respect to computer-assisted and/or roboticsurgical technology have contributed to advancements in the MIS andNOTES fields, including the ability to translate a surgeon's desiredsurgical actions into precise movements of surgical instruments inside abody cavity of a patient.

BRIEF SUMMARY

Despite recent developments in modern medical science and technology, itis recognized in the present disclosure that one or more problems areencountered in modern surgical technology and methodology. For example,a typical MIS procedure requires multiple incisions to a patient inorder to allow access via the incisions for the insertion of a cameraand various other laparoscopic instruments into the body cavity of thepatient.

As another example, surgical robotic systems oftentimes facedifficulties in providing, at the same time within a patient's cavity,left and right surgical robotic arms each having a main instrument (suchas a cutting or gripping instrument attached to the end of a surgicalrobotic arm) and one or more assistant instruments (such as a gripper,retractor, suction/irrigation, and/or image capturing device).

It is also recognized in the present disclosure that surgical roboticsystems face difficulties in providing an instrument, such as a cuttingor gripping instrument attached to the end of a surgical robotic arm,with access to all or even most parts, areas, and/or quadrants ofabdominal cavity of a patient. That is, after the surgical robotic armis inserted in the abdominal cavity of the patient and ready to performa surgical action, the instrument attached to the end of the surgicalrobotic arm is typically limited to access only certain parts, areas,and quadrants of the abdominal cavity of the patient.

In yet another example, known surgical robotic systems typically provideonly between one to two surgical robotic arms per access or opening(such as an incision or a natural orifice) of the patient. In thisregard, one or more additional incisions will be required for theinsertion of a camera and various laparoscopic instruments into theabdominal cavity of the patient.

Present example embodiments relate generally to and/or comprise systems,subsystems, processors, devices, logic, and methods for addressingconventional problems, including those described above.

DETAILED DESCRIPTION

It is recognized in the present disclosure that, despite recentdevelopments in medical science and technology, one or more problems areencountered in modern surgical technology and methodology, includingMIS. For example, a typical MIS procedure requires multiple incisions toa patient in order to allow access via the incisions for the insertionof a camera and various other laparoscopic instruments into the bodycavity of the patient.

In addition to the aforementioned disadvantages pertaining to themultiple and rather large incisions, it is recognized in the presentdisclosure that surgical robotic systems, including surgical roboticarms (and those instruments attached to them), developed for performingrobotic-assisted MIS surgical procedures also suffer from one or moreproblems. For example, it is recognized herein that a major technicalchallenge for a surgical robotic system is the difficulty in providingsufficient anchoring and/or reactive forces to stabilize against forcesthat are desired and/or necessary to be applied to the patient by thesurgical robotic system during a surgical action. In this regard,certain surgical actions for known surgical robotic systems may requiretremendous effort and time, and may not be performed properly or at allas a result of the problem of insufficient anchoring and/or reactiveforces.

Another example of a problem recognized in the present disclosure asbeing encountered by surgical robotic systems is the difficulty inproviding an instrument, such as a cutting and/or gripping instrumentattached to the end of a surgical robotic arm, with access to all oreven most parts, areas, and quadrants of an abdominal cavity of apatient after the surgical robotic system has been set up (or installed)and is ready to perform a surgery. That is, after the surgical roboticarm of the system has been inserted, attached, and properly set up inthe abdominal cavity of the patient and is ready to perform a surgicalaction, the instrument attached to the end of the surgical robotic armis typically limited to access only certain parts, areas, and quadrantsof the abdominal cavity of the patient. It is recognized in the presentdisclosure that such problems result in large from the limited number ofpossible degrees of freedom that can be provided by known surgicalrobotic systems and arms, and more specifically, the limited number ofin vivo degrees of freedom (i.e. the degrees of freedom provided withinan abdominal cavity of a patient) of known surgical robotic systems andarms. In this regard, surgical robotic systems typically provide onlybetween 2 to 4 in vivo degrees of freedom for each surgical robotic arm.

As another example, while known surgical robotic systems have beendesigned for use in an abdominal cavity of a patient to performforward-directed surgical procedures, such systems have not beendesigned for and may encounter problems when applied in situationsrequiring reverse-directed surgical procedures. For example, such knownsurgical robotic systems have not been designed for deployment through anatural orifice, such as a rectum or vagina, for performing naturalorifice transluminal endoscopic surgery (or NOTES), such astrans-vaginal gynecological procedures in women and trans-rectalurological procedures in men. Such systems may encounter one or moreproblems, such as the inability to access certain organs, tissues, orother surgical sites upon insertion into the natural orifice.

Surgical systems, devices, and methods, including those for use in MISand natural orifice transluminal endoscopic surgery (or NOTES), aredescribed in the present disclosure for addressing one or more problemsof known surgical systems, devices, and methods, including thosedescribed above and in the present disclosure. It is to be understoodthat the principles described in the present disclosure can be appliedoutside of the context of MIS and/or NOTES, such as performingscientific experiments and/or procedures in environments that are notreadily accessible by humans, including in a vacuum, in outer space,and/or under toxic and/or dangerous conditions, without departing fromthe teachings of the present disclosure.

The Surgical System (e.g., Surgical Device 200).

An illustration of an example embodiment of a surgical device or system(e.g., surgical device or system 200) operable to be inserted into anabdominal cavity of a patient through a single access or opening (e.g.,a single incision (such as an incision in or around the umbilical area)or through a natural orifice (such as a rectum or vagina, for performingnatural orifice transluminal endoscopic surgery (or NOTES), hereinafterreferred to as an “opening”) of the patient is depicted in FIG. 2A, FIG.2B, FIG. 2C, and FIG. 2D. The surgical device may then be anchored so asto position the surgical device 200 in the opening. The surgical device200 may comprise a port assembly 210 and an instrument arm assembly 230.The surgical device 200 may also comprise other elements, such as one ormore other instrument arm assemblies (e.g., instrument arm assembly240), one or more image capturing assemblies, one or more assistant armassemblies, etc.

The first distal elbow gear stage may also include a second distal elbowbevel gear (e.g., second distal elbow bevel gear 1125 a, as illustratedin at least FIGS. 12A, 12D, 14A, 14C, and 14D). The second distal elbowbevel gear 1125 a may be drivable by the first distal elbow bevel gear1124 a so as to rotate relative to axis C (the second distal elbow bevelgear 1125 a may have a central axis of rotation corresponding to axisC).

The distal elbow joint subassembly may include a third distal elbow gearstage. The third distal elbow gear stage may include a fourth distalelbow bevel gear (e.g., fourth distal elbow bevel gear 1131 a, asillustrated in at least FIGS. 12A, 14A, 14B, 14C, and 14D). The distalelbow joint subassembly may also include one or more connectors or thelike between the second distal elbow spur gear 1129 a and the fourthdistal elbow bevel gear 1131 a, such as connector 1130 a (as illustratedin at least FIG. 12A).

Alternatively, as illustrated in at least FIGS. 14B-D, the fourth distalelbow bevel gear 1131 a may be directly coupled (or connected orsecured) to the second distal elbow spur gear 1129 a in exampleembodiments, which is recognized in the present disclosure to enable areduction in total length of the arm assembly 230, 240.

The third distal elbow gear stage may also include a fifth distal elbowbevel gear (e.g., fifth distal elbow bevel gear 1132 a, as illustratedin at least FIGS. 12A and 14A-D). The fifth distal elbow bevel gear 1132a may be drivable by the fourth distal elbow bevel gear 1131 a so as torotate relative to axis C′ (the fifth distal elbow bevel gear 1132 a mayhave a central axis of rotation corresponding to axis C′).

A gear ratio between the fourth distal elbow bevel gear 1131 a and thefifth distal elbow bevel gear 1132 a may be between about 1:2 to 1:5(e.g., 1:3).

The distal elbow joint subassembly may include a fourth distal elbowgear stage. The fourth distal elbow gear stage may include a distalelbow planetary gear assembly (e.g., distal elbow planetary gearassembly 1133 a, as illustrated in at least FIGS. 11C, 12A, and 14A).The distal elbow joint subassembly may also include one or moreconnectors or the like (e.g., connector portion 1134 a) and/or the fifthdistal elbow bevel gear 1132 a and/or distal elbow sun gear 1133 aa mayhave an extended portion between the fifth distal elbow bevel gear 1132a and the distal elbow planetary gear assembly 1133 a, which isrecognized in the present disclosure to enable improved spacing forcabling to pass through the elbow coupling joint assembly 1120 (e.g.,pass through between the fifth distal elbow bevel gear 1132 a and thedistal elbow planetary gear assembly 1133 a).

Alternatively, as illustrated in at least FIGS. 11B and 12A, the fifthdistal elbow bevel gear 1132 a may be directly coupled (or connected orsecured) to the distal elbow planetary gear assembly 1133 a (i.e., thefifth distal elbow bevel gear 1132 a directly coupled or connected orsecured to distal elbow sun gear 1133 aa) in example embodiments.

FIG. 12B illustrates a side view and FIG. 12C illustrates an explodedperspective view of an example embodiment of the distal elbow planetarygear assembly 1133 a. The distal elbow planetary gear assembly 1133 amay have a central axis corresponding to axis C′. The distal elbowplanetary gear assembly 1133 a may include a distal elbow sun gear 1133aa. The distal elbow sun gear 1133 aa may be drivable by the fifthdistal elbow bevel gear 1132 a so as to rotate relative to axis C′. Thedistal elbow sun gear 1133 aa and/or the fifth distal elbow bevel gear1132 a may include an extended portion (not shown) so as to enable aspacing between the each other and allow for cabling to run through suchspacing.

The distal elbow planetary gear assembly 1133 a may also include aplurality of distal elbow planetary (or planet) gears 1133 ab. Forexample, the distal elbow planetary gear assembly 1133 a may include 4or more distal elbow planetary gears 1133 ab. Each of the distal elbowplanetary gears 1133 ab may be configured to rotate relative to itscentral axis. The distal elbow planetary gears 1133 ab may be drivableby the distal elbow sun gear 1133 aa to collectively rotate around axisC′.

The distal elbow planetary gear assembly 1133 a may also include adistal elbow ring gear 1133 ac. The distal elbow ring gear 1133 ac maybe fixed or locked from rotating relative to axis C′ in exampleembodiments so as to enable the plurality of distal elbow planetarygears 1133 ab to collectively rotate around axis C′.

The distal elbow planetary gear assembly 1133 a may also include adistal elbow planetary gear carrier 1133 ad. The distal elbow planetarygear carrier 1133 ad may have a plurality of first ends 1133 ad′connected to plurality of distal elbow planetary gears 1133 ab. Thedistal elbow planetary gear carrier 1133 ad may also have a second end1133 ad″ connected to a portion of the distal end 1100 b of the forearmsegment 1100.

In this regard, when the distal elbow sun gear 1133 aa is driven by thefifth distal elbow bevel gear 1132 a to rotate relative to axis C′, thedistal elbow sun gear 1133 aa in turn drives the plurality of distalelbow planetary gears 1133 ab to collectively rotate relative to axisC′. Such collective rotation of the plurality of distal elbow planetarygears 1133 ab around axis C′ in turn drives the distal elbow planetarygear carrier 1133 ad to rotate relative to axis C′ (via the connectionbetween the first ends 1133 ad′ of the distal elbow planetary gearcarrier 1133 ad and the plurality of distal elbow planetary gears 1133ab). Such rotation of the distal elbow planetary gear carrier 1133 adaround axis C′ in turn drives the forearm segment 1100 to rotate (orpivotally rotate) relative to axis C′ (e.g., in the Direction C′, asillustrated in at least FIG. 11C) (via the connection between the secondend 1133 ad″ of the distal elbow planetary gear carrier 1133 ad and thedistal end 1100 b of the forearm segment 1100).

A gear ratio between the fifth distal elbow bevel gear 1132 a and thedistal elbow planetary gear assembly 1133 a may be between about 1:2 to1:8 (e.g., 1:5).

Accordingly, the forearm segment 1100 may be driven to rotate (orpivotally rotate) relative to axis C′ (or rotate relative to the distalelbow joint 1120 a) by driving the first distal motor 1142, which inturn drives the first distal elbow gear stage (which includes the firstdistal elbow bevel gear 1124 a, the second distal elbow bevel gear 1125a, the third distal elbow bevel gear 1126 a), which in turn drives thesecond distal elbow gear stage (which includes the first distal elbowspur gear 1128 a and the second distal elbow spur gear 1129 a), which inturn drives the third distal elbow gear stage (which includes the fourthdistal elbow bevel gear 1131 a and the fifth distal elbow bevel gear1132 a), which in turn drives the fourth distal elbow gear stage (whichincludes the distal elbow planetary gear assembly 1133 a having thedistal elbow sun gear 1133 aa, the distal elbow planetary gears 1133 ab,the distal elbow ring gear 1133 ac, and the distal elbow planetary gearcarrier 1133 ad), which in turn drives the forearm segment 1100 torotate relative to axis C′.

A gear or magnification ratio for the distal elbow joint assembly may bebetween about 1:20 to 1:50 (e.g., 1:30).

The distal elbow joint assembly may be or include any other gearconfiguration for driving the forearm segment 1100, including thosedescribed in the present disclosure. For example, the distal elbow jointassembly may include any one or more configurations or combinations ofgears and/or gear assemblies, including straight gear configurations,planetary gear configurations, beveled gear configurations, spiralbeveled gear configurations, hypoid gear configurations, helical gearconfigurations, worm gear configurations, and/or any other gear and/ormechanical configurations (such as wire and pulley) without departingfrom the teachings of the present disclosure.

(ii) The Proximal Elbow Joint Subassembly.

In an example embodiment, the second distal motor 1144 may drive theproximal elbow joint subassembly so as to cause the distal elbow joint1120 a (and the forearm segment 1100 attached to the distal elbow joint1120 a) to rotate (or pivotally rotate) relative to the proximal elbowjoint 1120 b (or relative to axis C, as depicted by the Direction Cillustrated in FIG. 11B).

Put differently, the second distal motor 1144 may drive the proximalelbow joint subassembly so as to cause the forearm segment 1100 (whichis attached to the distal elbow joint 1120 a) to rotate (or pivotallyrotate) relative to the proximal elbow joint 1120 b (or relative to axisC, as depicted by the Direction C illustrated in FIG. 11B). Asillustrated in at least FIGS. 11B, 11C, 12A, 12D, and 14A-D, theproximal elbow joint subassembly includes a plurality of gears. Morespecifically, the proximal elbow joint subassembly includes a gear trainsystem having a plurality of gear stages.

The proximal elbow joint subassembly may include a first proximal elbowgear stage. The first proximal elbow gear stage may include a firstproximal elbow bevel gear (e.g., first proximal elbow bevel gear 1122 b,as illustrated in at least FIGS. 12D, 14C, and 14D). The proximal elbowjoint subassembly may also include one or more gears between the seconddistal motor drive portion 1144 a and the first proximal elbow bevelgear 1122 b, such as one or more spur gears (not shown). The proximalelbow joint subassembly may also include one or more connectors or thelike between the second distal motor drive portion 1144 a and the firstproximal elbow bevel gear 1122 b, such as connector 1121 b (asillustrated in at least FIG. 12D).

Alternatively, as illustrated in at least FIGS. 14C and 14D, the firstproximal elbow bevel gear 1122 b may be configured so as to be drivendirectly by the second distal motor drive portion 1144 a in exampleembodiments (as shown in at least FIGS. 14C and 14D), which isrecognized in the present disclosure to enable a reduction in totallength of the arm assembly 230, 240.

The first proximal elbow gear stage may also include a second proximalelbow bevel gear (e.g., second proximal elbow bevel gear 1123 b, asillustrated in at least FIGS. 12D, 14C, and 14D). The second proximalelbow bevel gear 1123 b may be drivable by the first proximal elbowbevel gear 1122 b so as to rotate relative to axis C (the secondproximal elbow bevel gear 1123 b may have a central axis of rotationcorresponding to axis C).

A gear ratio between the first proximal elbow bevel gear 1122 b and thesecond proximal elbow bevel gear 1123 b may be between about 1:2 to 1:5(e.g., 1:3).

The proximal elbow joint subassembly may include a second proximal elbowgear stage. The second proximal elbow gear stage may include a proximalelbow planetary gear assembly (e.g., proximal elbow planetary gearassembly 1124 b, as illustrated in at least FIGS. 11B, 12D, and 14C).The proximal elbow joint subassembly may also include one or moreconnectors (not shown) and/or the second proximal elbow bevel gear 1123b and/or proximal elbow sun gear 1124 ba may have an extended portionbetween the second proximal elbow bevel gear 1123 b and the proximalelbow planetary gear assembly 1124 b (not shown), which is recognized inthe present disclosure to enable improved spacing for cabling to passthrough the elbow coupling joint assembly 1120 (e.g., pass throughbetween the second proximal elbow bevel gear 1123 b and the proximalelbow planetary gear assembly 1124 b).

Alternatively, as illustrated in at least FIGS. 11C, 12D, and 14C, thesecond proximal elbow bevel gear 1123 b may be directly coupled (orconnected or secured) to the proximal elbow planetary gear assembly 1124b (i.e., the second proximal elbow bevel gear 1123 b directly coupled orconnected or secured to proximal elbow sun gear 1124 ba) in exampleembodiments.

FIG. 12E illustrates a side view and FIG. 12F illustrates an explodedperspective view of an example embodiment of the proximal elbowplanetary gear assembly 1124 b. The proximal elbow planetary gearassembly 1124 b may have a central axis corresponding to axis C. Theproximal elbow planetary gear assembly 1124 b may include a proximalelbow sun gear 1124 ba. The proximal elbow sun gear 1124 ba may bedrivable by the second proximal elbow bevel gear 1123 b so as to rotaterelative to axis C. The proximal elbow sun gear 1124 ba and/or thesecond proximal elbow bevel gear 1123 b may include an extended portionso as to enable a spacing between the each other and allow for cablingto run through such spacing.

The proximal elbow planetary gear assembly 1124 b may also include aplurality of proximal elbow planetary (or planet) gears 1124 bb. Forexample, the proximal elbow planetary gear assembly 1124 b may include 4or more proximal elbow planetary gears 1124 bb. Each of the proximalelbow planetary gears 1124 bb may be configured to rotate relative toits central axis. The proximal elbow planetary gears 1124 bb may bedrivable by the proximal elbow sun gear 1124 ba to collectively rotatearound axis C.

The proximal elbow planetary gear assembly 1124 b may also include aproximal elbow ring gear 1124 bc. The proximal elbow ring gear 1124 bcmay be fixed or locked from rotating relative to axis C in exampleembodiments so as to enable the plurality of proximal elbow planetarygears 1124 bb to collectively rotate around axis C.

The proximal elbow planetary gear assembly 1124 b may also include aproximal elbow planetary gear carrier 1124 bd. The proximal elbowplanetary gear carrier 1124 bd may have a plurality of first ends 1124bd′ connected to the plurality of proximal elbow planetary gears 1124bb. The proximal elbow planetary gear carrier 1124 bd may also have asecond end 1124 bd″ connected to a portion of a proximal end of thedistal elbow joint 1120 a.

In this regard, when the proximal elbow sun gear 1124 ba is driven bythe second proximal elbow bevel gear 1123 b to rotate relative to axisC, the proximal elbow sun gear 1124 ba in turn drives the plurality ofproximal elbow planetary gears 1124 bb to collectively rotate relativeto axis C. Such collective rotation of the plurality of proximal elbowplanetary gears 1124 bb around axis C in turn drives the proximal elbowplanetary gear carrier 1124 bd to rotate relative to axis C (via theconnection between the first ends 1124 bd′ of the proximal elbowplanetary gear carrier 1124 bd and the plurality of proximal elbowplanetary gears 1124 bb). Such rotation of the proximal elbow planetarygear carrier 1124 bd around axis C in turn drives the distal elbow joint1120 a to rotate (or pivotally rotate) relative to axis C (e.g., in theDirection C, as illustrated in at least FIG. 11B) (via the connectionbetween the second end 1124 bd″ of the proximal elbow planetary gearcarrier 1124 bd and the proximal end of the distal elbow joint 1120 a).

A gear ratio between the second proximal elbow bevel gear 1123 b and theproximal elbow planetary gear assembly 1124 b may be between about 1:2to 1:8 (e.g., 1:5).

Accordingly, distal elbow joint 1120 a (and the forearm segment 1100attached to the distal elbow joint 1120 a) may be driven to rotate (orpivotally rotate) relative to axis C (or rotate relative to the proximalelbow joint 1120 b) by driving the second distal motor 1144, which inturn drives the first proximal elbow gear stage (which includes thefirst proximal elbow bevel gear 1122 b and the second proximal elbowbevel gear 1123 b), which in turn drives the second proximal elbow gearstage (which includes the proximal elbow planetary gear assembly 1124 bhaving the proximal elbow sun gear 1124 ba, the proximal elbow planetarygears 1124 bb, the proximal elbow ring gear 1124 bc, and the proximalelbow planetary gear carrier 1124 bd), which in turn drives the distalelbow joint 1120 a (and the forearm segment 1100 attached to the distalelbow joint 1120 a) to rotate relative to axis C.

Put differently, the forearm segment 1100 (which is attached to thedistal elbow joint 1120 a) may be driven to rotate (or pivotally rotate)relative to axis C (or rotate relative to the proximal elbow joint 1120b) by driving the second distal motor 1144, which in turn drives thefirst proximal elbow gear stage (which includes the first proximal elbowbevel gear 1122 b and the second proximal elbow bevel gear 1123 b),which in turn drives the second proximal elbow gear stage (whichincludes the proximal elbow planetary gear assembly 1124 b having theproximal elbow sun gear 1124 ba, the proximal elbow planetary gears 1124bb, the proximal elbow ring gear 1124 bc, and the proximal elbowplanetary gear carrier 1124 bd), which in turn drives the forearmsegment 1100 (which is attached to the distal elbow joint 1120 a) torotate relative to axis C.

A gear or magnification ratio for the proximal elbow joint assembly maybe between about 1:10 to 1:30 (e.g., 1:20).

The proximal elbow joint assembly may be or include any other gearconfiguration for driving the forearm segment 1100, including thosedescribed in the present disclosure. For example, the proximal elbowjoint assembly may include any one or more configurations orcombinations of gears and/or gear assemblies, including straight gearconfigurations, planetary gear configurations, beveled gearconfigurations, spiral beveled gear configurations, hypoid gearconfigurations, helical gear configurations, worm gear configurations,and/or any other gear and/or mechanical configurations (such as wire andpulley) without departing from the teachings of the present disclosure.

Putdifferently, the distal shoulder joint 1160 a may be configured toenable the upper arm segment 1140 to rotate (or pivotally rotate)relative to the distal shoulder joint 1160 a. As further described belowand in the present disclosure, such rotation relative to axis D may bedriven by the first proximal motor 1146 and distal shoulder jointsubassembly.

The proximal shoulder joint 1160 b may have an axis of rotation E, asillustrated in at least FIGS. 11B, 11C, 13A, 13D, and 15A-D. Theproximal shoulder joint 1160 b may be configured to enable the distalshoulder joint 1160 a (and the upper arm segment 1140 attached to thedistal shoulder joint 1160 a) to rotate (or pivotally rotate) relativeto axis E. Put differently, the proximal shoulder joint 1160 b may beconfigured to enable the distal shoulder joint 1160 a (and the upper armsegment 1140 attached to the distal shoulder joint 1160 a) to rotate (orpivotally rotate) relative to the proximal shoulder joint 1160 b.

Put differently, the proximal shoulder joint 1160 b may be configured toenable the upper arm segment 1140 to rotate (or pivotally rotate)relative to the proximal shoulder joint 1160 b. The rotational axis E ofproximal shoulder joint 1160 b may not be parallel to the rotationalaxis D of the distal shoulder joint 1160 a. For example, the rotationalaxis E of proximal shoulder joint 1160 b may be orthogonal to therotational axis D of the distal shoulder joint 1160 a. As furtherdescribed below and in the present disclosure, such rotation relative toaxis E may be driven by the second proximal motor 1148 and proximalshoulder joint subassembly.

The distal shoulder planetary gear assembly 1170 a may also include adistal shoulder ring gear 1170 ac. The distal shoulder ring gear 1170 acmay be fixed or locked from rotating relative to axis D in exampleembodiments so as to enable the plurality of distal shoulder planetarygears 1170 ab to collectively rotate around axis D.

The distal shoulder planetary gear assembly 1170 a may also include adistal shoulder planetary gear carrier 1170 ad. The distal shoulderplanetary gear carrier 1170 ad may have a plurality of first ends 1170ad′ connected to the plurality of proximal elbow planetary gears 1170ab. The distal shoulder planetary gear carrier 1170 ad may also have asecond end 1170 ad″ connected to a portion of a proximal end 1140 b ofthe upper arm segment 1140.

In this regard, when the distal shoulder sun gear 1170 aa is driven bythe second distal shoulder bevel gear 1169 a to rotate relative to axisD, the distal shoulder sun gear 1170 aa in turn drives the plurality ofdistal shoulder planetary gears 1170 ab to collectively rotate relativeto axis D. Such collective rotation of the plurality of distal shoulderplanetary gears 1170 ab around axis D in turn drives the distal shoulderplanetary gear carrier 1170 ad to rotate relative to axis D (via theconnection between the first ends 1170 ad′ of the distal shoulderplanetary gear carrier 1170 ad and the plurality of distal shoulderplanetary gears 1170 ab). Such rotation of the distal shoulder planetarygear carrier 1170 ad around axis C in turn drives the upper arm segment1140 to rotate (or pivotally rotate) relative to axis D (e.g., in theDirection D, as illustrated in at least FIG. 11C) (via the connectionbetween the second end 1170 ad″ of the distal shoulder planetary gearcarrier 1170 ad and the proximal end 1140 b of the upper arm segment1140).

A gear ratio between the second distal shoulder bevel gear 1169 a andthe distal shoulder planetary gear assembly 1170 a may be between about1:2 to 1:8 (e.g., 1:5).

Accordingly, the upper arm segment 1140 may be driven to rotate (orpivotally rotate) relative to axis D (or relative to the distal shoulderjoint 1160 b) by driving the first proximal motor 1146, which in turndrives the first distal shoulder gear stage (which includes the firstdistal shoulder bevel gear 1168 a and the second distal shoulder bevelgear 1169 a), which in turn drives the second distal shoulder gear stage(which includes the distal shoulder planetary gear assembly 1170 ahaving the distal shoulder sun gear 1170 aa, the distal shoulderplanetary gears 1170 ab, the distal shoulder ring gear 1170 ac, and thedistal shoulder planetary gear carrier 1170 ad), which in turn drivesthe upper arm segment 1140 to rotate relative to axis D.

A gear or magnification ratio for the distal shoulder joint assembly maybe between about 1:20 to 1:50 (e.g., 1:30).

The distal shoulder joint assembly may be or include any other gearconfiguration for driving the upper arm segment 1140, including thosedescribed in the present disclosure.

Alternatively, as illustrated in at least FIGS. 11C and 13A, the fifthproximal shoulder bevel gear 1172 b may be directly coupled (orconnected or secured) to the proximal shoulder planetary gear assembly1173 b (i.e., the fifth proximal shoulder bevel gear 1172 b directlycoupled or connected or secured to the proximal shoulder sun gear 1173ba) in example embodiments.

FIG. 13B illustrates a side view and FIG. 13C illustrates an explodedperspective view of an example embodiment of the proximal shoulderplanetary gear assembly 1173 b.

Put differently, the upper arm segment 1140 (which is attached to thedistal shoulder joint 1160 a) may be driven to rotate (or pivotallyrotate) relative to axis E (or relative to the proximal shoulder joint1160 b) by driving the second proximal motor 1148, which in turn drivesthe first proximal shoulder gear stage (which includes the firstproximal shoulder bevel gear 1163 b, the second proximal shoulder bevelgear 1164 b, the third proximal shoulder bevel gear 1165 b), which inturn drives the second proximal shoulder gear stage (which includes thefirst proximal shoulder spur gear 1167 b, the second proximal shoulderspur gear 1168 b, and the third proximal shoulder spur gear 1169 b),which in turn drives the third proximal shoulder gear stage (whichincludes the fourth proximal shoulder bevel gear 1171 b and the fifthproximal shoulder bevel gear 1172 b), which in turn drives the fourthproximal shoulder gear stage (which includes the proximal shoulderplanetary gear assembly 1173 b having the proximal shoulder sun gear1173 ba, the proximal shoulder planetary gears 1173 bb, the proximalshoulder ring gear 1173 bc, and the proximal shoulder planetary gearcarrier 1173 bd), which in turn drives the the upper arm segment 1140(which is attached to the distal shoulder joint 1160 a) to rotaterelative to axis E.

A gear or magnification ratio for the proximal shoulder joint assemblymay be between about 1:20 to 1:50 (e.g., 1:30).
